Depreciation Methods for UAE Corporate Tax: A Practical Guide

Depreciation is the process of spreading the cost of a fixed asset over its useful life. For corporate tax purposes, depreciation reduces your taxable income — the more you can legitimately depreciate, the less tax you pay.

With the introduction of UAE corporate tax at 9%, depreciation has become a meaningful tax planning tool. A company that buys AED 500,000 worth of equipment does not deduct AED 500,000 in year one (in most cases). Instead, the cost is spread over the asset's useful life, creating a deduction in each year.

The most common method. The cost of the asset is divided equally over its useful life.

Formula: Annual depreciation = (Cost - Residual value) / Useful life

This means AED 9,000 is deductible from your taxable income each year for 5 years. At the 9% corporate tax rate, that saves AED 810 in tax annually.

Straight-line is simple, predictable, and universally accepted for UAE tax purposes.

An accelerated method where higher depreciation is charged in the early years and lower amounts in later years.

Formula: Annual depreciation = Book value at start of year x Depreciation rate

This method front-loads the deduction, which can be advantageous for tax planning — you get larger tax savings in the early years when cash flow is often tightest.

The UAE corporate tax law does not prescribe specific depreciation rates for all asset classes. Instead, it relies on accounting standards (IFRS) to determine useful lives. However, typical useful lives for common asset types are:

• Office furniture and fixtures: 5-10 years
• Computer equipment: 3-5 years
• Vehicles: 4-5 years
• Office improvements / fit-out: Life of the lease (or 5-10 years)
• Software: 3-5 years
• Machinery and equipment: 5-15 years, depending on the type
• Buildings: 25-50 years (rare for free zone companies that lease)

Choose useful lives that reflect the actual expected use of the asset. An auditor will challenge a 3-year useful life for office furniture or a 10-year life for a laptop.

Let us work through a concrete example for a free zone company:

Scenario: Your company earns AED 1,000,000 in revenue with AED 600,000 in operating expenses (before depreciation). You purchased AED 200,000 in equipment during the year with an average useful life of 5 years.

Without depreciation deduction: Taxable income: AED 1,000,000 - AED 600,000 = AED 400,000 Tax (9% on amount above AED 375,000): 9% x AED 25,000 = AED 2,250

With depreciation deduction (straight-line): Depreciation: AED 200,000 / 5 = AED 40,000 Taxable income: AED 1,000,000 - AED 600,000 - AED 40,000 = AED 360,000 Tax: AED 0 (below AED 375,000 threshold)

In this example, proper depreciation accounting saves AED 2,250 in tax. Over 5 years, the total depreciation deduction of AED 200,000 saves approximately AED 18,000 in corporate tax.

Every fixed asset should be recorded in an asset register that tracks:

• Asset description and category
• Purchase date and cost
• Depreciation method and rate
• Monthly/annual depreciation amount
• Accumulated depreciation
• Net book value

Maya Finance includes a fixed assets module that handles this automatically. When you categorize a purchase as a fixed asset, the system creates the asset register entry, applies the appropriate depreciation method, and posts monthly depreciation journal entries to your books. At year-end, the depreciation schedule is ready for your tax filing.
